+# z26 is written partly in x86 (32-bit) assembly, so it can't be built
+# for 64-bit. So the solution for running it on pure 64-bit systems is
+# to use a static binary that doesn't require any 32-bit libs.
+
+# Run this script on a 32-bit host *with VDSO disabled*, to generate
+# the binary used for the 64-bit build.
+
+# Notes:
+# - libgcc_s.so has to be included or else z26 dumps core on exit.
+# - libaoss and libasound are needed because z26 doesn't use SDL's
+#   sound API, it talks directly to OSS via /dev/dsp.
+# - libudev is needed for SDL to detect the mouse.
+# - If you run "file" on the statified binary, it looks dynamic:
+#   $ file /usr/games/z26 
+#   /usr/games/z26: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, stripped
+#   ...but ldd says it's "not a dynamic executable". This is normal
+#   for statified binaries.
+# - Do not attempt to strip the statified binary. It will break.
